I am swapping an (expensive) ZF5 into my 1990 F250 which currently has an M5R2. In comparing the two trannys they both look like similar lengths and dimensions and based on internet research the swap should be fairly smooth.

While I'm in there I'm going to change the clutch (luk) and slave (Motorcraft). In my internet research I found a few threads with people talking about "Dual mass flywheel" and "single mass flywheels." I am planning on inspecting the flywheel and possibly having it resurfaced or replaced. Should I pay any attention to this DMF and SMF stuff? Does it even apply to my 5.0?

Thank you..

 

dual mass was only on diesels
